BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a liquid circulator for a bathtub or a foot dipping tank, more particularly a liquid circulator structure that does not require a liquid circulation pipeline.

2. Description of the Related Art

A traditional messaging bath tub or foot dipping tank as shown in FIG. 1 usually comes with a liquid circulating structure for producing a water circulation, and the liquid circulator structure has at least one water incoming pipeline 1, and the water incoming pipeline 1 is interconnected to a compressed motor 2, and the compressed motor 2 interconnects at least one water outgoing pipe 3 to a tank, and the water incoming pipeline 1 guides the water of the tank into the compressed motor 2. After the motor 2 is compressed, the water flows from the water outgoing pipeline 3 into the tank, so that the liquid circulating structure can produce a whirl of water circulation in the tank. The impact produced by the whirl has a messaging effect on human bodies. Further, various medical agents can be added to the water for a bath for the medical treatment. After the use of a messaging bathtub or a foot dipping tank is completed, it is necessary to drain out the water and medical agents in the tank or refill the tank to facilitate the next use or storage. However, some liquid may remain on the water incoming pipeline 1 and the water outgoing pipeline 3 of the prior-art liquid circulating structure, and thus it will cause hygienic problems. Therefore, it is necessary for users to clean up the internal pipelines of the traditional liquid circulating structure, which is very inconvenient to users.

After each section of the forgoing structure is described in details, the principle and method for the actions of the present invention are described as follows:

Please refer to FIGS. 4A and 4B for the illustrative views of the conventional foot dipping message tank according to a preferred embodiment of the present invention. By the actions of the fixing section 12 and the screw nut 121 according to the present invention, we only need to drill a hole at an appropriate position of the tank in the manufacturing process as to mount the whole set of liquid circulator onto the wall of the tank by a screw nut 121. Such arrangement not only provides a simple and easy installation, but also allows user to install the liquid circulator horizontally or vertically according to the user's need. Further, since the bottom of the circulating base 10 is completely isolated and sealed from the outside and the water stop washer 111 at the bottom surface of the connecting section 11 can be secured by a screw nut 121 and the wall of the tank can stop the action of the water circulation as shown in FIG. 5A to prevent the liquid from leaking and relieve your worry about electric leakage of the motor 40 caused by moisture.

Further, with the installation of the upper fixing axle center 211 and the lower fixing axle center 131, the vane set 20 not only secures the rotary axle center of the vane base 21, but also rotates the vane base 21 smoother by installing the bearings 132, 212.

When the motor 40 is driven to rotate by electric power, the axle 41 can drive the rotary magnetic base 42 to rotate outside the accommodating chamber 13. The rotary magnetic base 42 can drive the vane base 21 to rotate with the accommodating chamber in between due to the magnetic force between the rotary magnetic base 42 and the rotary magnetic core 23. Further, if the vane base 21 is rotated counterclockwise by the action of the circulating vanes 22 as shown in FIG. 5B, the circulating vanes 22 can drive the water to flow towards the center of the vane base 21 and pass through the through hole 312 of the fixed frame 311 and then flow out from the water outlet hole 31 to produce a whirl of water current.

When the vanes 22 are rotating, the pressure difference produced by the speeds of fluid will drive the water to produce a sucking force and suck the air from the air incoming hole 24 to produce an air exposure action with the water current and enhance the water circulating massage effect. Further, a stop valve can be installed to the air pipe 141 to prevent the water in the tank from refluxing and leaking, and the air pipe 141 can also be connected to an air pump to produce high-pressure air and the air is pumped into the water current through the air incoming hole 24.

The present invention does not require the internal pipeline disposed in the liquid circulating structure as needed in the prior art, and thus can avoid the cleaning of the internal pipelines and also can avoid the hygienic problem caused by the liquid remained on the pipelines. Furthermore, the present invention is easy and simple to install and does not need to install the internal pipelines, and thus can be used in a horizontal position or a vertical position according to the user's need to increase the flexibility of the manufacture of the massaging tank and effectively simplify the manufacturing process.

In summation of the above description, the present invention herein enhances the performance than the conventional structure and further complies with the patent application requirements and is submitted to the Patent and Trademark Office for review and granting of the commensurate patent rights.
